Abstract	The titled properties on reduction of the perovskite LaBO3 (B = Fe, Co, Ni) have been investigated by means of temperature-programmed reduction, isothermal reduction and X-ray diffraction methods. Nominal composition of LaFeO3.18, LaCoO3.00 and LaNiO2.92 are determined. Reduction reaction of these mixed oxides differed according to B-site transition metal and thermal stability on reduction decreased as following order: LaFeO3.18 > LaCoO3.00 > LaNiO2.92. From the results of isothermal reaction, kinetics on reduction of the perovskite has been discussed in detail.
